Class Codes & Rates:

Code 1701 is applied to insureds engaged in the manufacture of cement. The raw materials (limestone, marl, alumina, lime, iron oxide and magnesia) are received, crushed, blended and sized in rock crushing, rough milling and screening equipment. The material is ground by either a wet or dry process but largely in ball or tube mills followed by blending in proportioning equipment. Very large, continuous rotary kilns are generally used. The final process is finish-grinding prior to storing in silos or sacking in paper bags.
